What is a Microcontroller?
Even if you’re new to programming and electronics, I’m sure you’ve heard about microcontroller boards at some point in your life: in school, college, work, etc. It has become a household name in the electronics industry. A microcontroller board is a tiny computer with the main component being a metal oxide semiconductor circuit chip. The essential building blocks of all microcontrollers, such as the central processing unit (CPU), input/output (I/O), memory, and peripherals, are the same (programmable).
Microcontrollers are exciting things that one can not even imagine. They are also beneficial in many ways and are one of the essential elements of any computer.
Control devices, automotive engines, remote controls, appliances, power tools, toys, implanted medical devices, and other embedded systems require microcontrollers because of their capabilities.
They are the primary choice for DIY projects and learning for engineers, enthusiasts, and programmers.
What is a Microprocessor?
A microprocessor is a small electrical device found on the motherboard of a computer that contains the logic, arithmetic, and control circuitry required to perform the functions of a digital computer’s central processing unit (CPU). It is a crucial electronic component of a computer that allows it to accomplish its functions efficiently.
It’s also known as a central processing unit, and it’s made up of millions of tiny components like as diodes, transistors, and resistors all working together on a single integrated circuit chip.
Earlier generations of microprocessors around the turn of the twentieth century required many chips to perform computer operations. Microprocessors assist in various tasks, from managing elevators to browsing the Internet.
All that a computer performs is described by computer program instructions. To fulfill the computer’s functions, the microprocessor runs these commands millions of times every second.
I hope you’ve gained a better grasp of microcontrollers and microprocessors as a result of this tutorial. Keeping this in mind, we’ll now turn our attention to the crucial topic of ‘Arduino vs. Raspberry Pi.’ So, let’s take a closer look at each of these two boards individually.
History of Raspberry Pi and Arduino
In 2012, the Raspberry Pi revolutionized the single-board computer market by costing $35, compared to three to five times the price of a comparable board at the time. The Raspberry Pi team expected to sell roughly 10,000 boards to students and the general public to assist university students in gaining first-hand skills for their courses.
After eight years and over 30 million board sales, the Raspberry Pi has established itself as a significant maker/education/hobbyist player. The Raspberry Pi can be used in electronics projects ranging from a simple flashing LED to delicate scientific data collecting and intricate robotics. It is a full computer that runs a genuine Linux OS with thousands of programs.
Arduino was conceived in 2005 as a tool for students at the Ivrea Interaction Design Institute. In their creations, the students used the BASIC Stamp microcontroller. Nonetheless, the Arduino and the Wiring language used to write code for ATmega-based boards were designed to save money and provide flexibility. Since then, numerous different Arduino versions have been released, but the Arduino Uno has remained the most popular among makers.
What is Arduino?
Let’s have a look at Arduino first. Massimo Banzi Et Al. in Ivrea, Italy, invented Arduino. Arduino is an open-source hardware and software electronics prototyping tool. Arduino is a Microcontroller development board that may be used to blink LEDs, accept input from buttons, read data from sensors, drive motors, and perform a variety of other “Microcontroller” functions.
The Arduino UNO, based on Atmel’s ATmega328P microcontroller, is the most popular Arduino board (now Microchip). When it comes to Arduino’s software, there are a few options. All of the boards can be programmed in C and C++ using a unique tool called Arduino IDE. The Arduino IDE includes all necessary toolchains for editing source code, compiling, and programming the Arduino board’s Microcontroller.
If you’ve worked with microcontrollers before, such as the 8051, Atmel, or PIC, you know how time-consuming it can be to create applications for them. Let’s look at the process if you’re unfamiliar with it.
First, use a specific IDE (Keil, Atmel Studio, or PIC’s MPLAB IDE) to write the application software (main source code). After that, you must compile the code and create a binary file in the form of an a.hex file. You must now use programmer software to upload the hex file to the target microcontroller, which requires specific hardware called a “programmer.”
With its plug-and-play method of quick programming, Arduino made this procedure much easier. You may write the code, compile it, and upload it to the Microcontroller using a single piece of software (the Arduino IDE). You won’t need any additional hardware to upload the application. Connect the Arduino board to a computer via USB, press the upload button, and the Microcontroller on the Arduino board is ready to work.
Another benefit of Arduino is that it is open-source. This means that the design files for software and libraries and the source code are freely available. The hardware design files can be used as a starting point for building your own Arduino board.
What is Raspberry Pi?
The Raspberry Pi was created at the University of Cambridge in the United Kingdom by Eben Christopher Upton, the Welsh CEO of Raspberry Pi (Trading) Ltd, and released in 2012. It has undergone numerous alterations and changes since then.
The Raspberry Pi Foundation, a UK organization, developed a series of single-board computers with that name. Its goal is to educate people about computers and make computing education more accessible worldwide.
The difference between Arduino and Raspberry Pi is that Arduino is a Microcontroller-based development board. In contrast, Raspberry Pi is a Microprocessor-based computing board (typically an ARM Cortex-A Series).
A keyboard and mouse (through USB), monitor (by AV Port or HDMI), camera (via the specific Camera Interface), and the Internet (via Ethernet or Wi-Fi) can all be connected to the Raspberry Pi in the same way they can to a desktop computer.
Because the whole computer components, such as the processor, RAM, graphics, storage, connectors, and so on, are built on a single PCB, the Raspberry Pi and other comparable boards are referred to as Single Board Computers or SBCs.
The Raspberry Pi can run an operating system because it is a full computer. The Raspberry Pi Foundation is in charge of designing and developing the Raspberry Pi SBC and providing a Debian-based Linux distribution known as the Raspberry Pi OS, previously known as the Raspbian OS.
The Raspberry Pi also runs Linux, which allows software to be created in a variety of programming languages including Python, Java,C, C++, HTML, and others.
Its original goal was to promote programming languages like Python and Scratch in schools. Still, it quickly acquired appeal among hobbyists, DIY builders, and enthusiasts for creating various applications such as weather stations, robotics, and camera-based security systems.
Because of its success and popularity, new versions of the Raspberry Pi are released regularly, the most recent of which is the Raspberry Pi 4 Model B. The RAM, CPU, and ROM are all found on the Arduino board’s Microcontroller. It’s vital to remember that the hardware design files and firmware for the Raspberry Pi aren’t open-source.
Arduino vs Raspberry Pi: What’s The Difference?
Arduino and Raspberry Pi are excellent teaching tools for students, amateurs, and enthusiasts. Let’s look at some distinctions between the Raspberry Pi and the Arduino.
- The most significant distinction is that Raspberry Pi is a microprocessor-based small computer , whereas Arduino is a microcontroller board.
- The Arduino board’s Microcontroller contains the Central Processing Unit (CPU), Random Access Memory (RAM), and Read Only Memory (ROM). The Arduino Board’s additional hardware is used for IO communication, power and programming. With a processor, memory, storage, graphics driver, and ports on the board, the Raspberry Pi SBC offers all of the features of a computer.
- Raspberry Pi requires an operating system to function. No operating system is necessary for Arduino. All you need is a compiled source code binary.
- Raspberry Pi OS is a fully functional operating system that comes pre-installed on the device (previously known as Raspbian OS). Although the Raspberry Pi may run on various operating systems, the Raspberry Pi Foundation prefers Linux. If you like, you can install Android. There is no operating system on Arduino. All you need is firmware that tells the Microcontroller what to do.
- This isn’t to say that we can’t use Raspberry Pi to connect sensors and LEDs. The Raspberry Pi has a 40-pin GPIO, which may connect various electronic components such as LEDs, Buttons, Sensors, Motors, and so on, to facilitate learning programming by controlling hardware. Digital IO (Digital Input and Output) and Analog IN (Analog Input and Output) are the terms used on Arduino to describe the GPIO (for Analog Input).
- Arduino Shields, which plug into the Arduino Pin headers, allow you to add a specific feature or capability to your project. Such components include touchscreens, motor drivers, SD Card Readers, Wi-Fi, Ethernet connections, and cameras. Although the Raspberry Pi is a self-contained board, it may be expanded with additional components such as RGB panels,touchscreen or GPS.
- The Raspberry Pi HAT Expansion Boards, also known as HAT Expansion Boards, are based on Arduino Shields, which may be used to extend the capability of the Raspberry Pi. The GPIO Pins are connected to them.
- Raspberry Pi and Arduino have radically different power requirements. Even though they are both powered by USB (the Raspberry Pi via micro-USB or USB Type C and the Arduino via USB Type B), the Raspberry Pi requires more current than the Arduino. So, although Raspberry Pi needs a power adapter, Arduino may be powered directly from a computer’s USB port.
- The Raspberry Pi’s hardware, software, and applications may be damaged if the power is interrupted. A power failure prompts Arduino to restart. As a result, the Raspberry Pi must be properly shut down before disconnecting power.
- For code development, Arduino employs the Arduino IDE, Python IDLE, Eclipse IDE, or any other Linux-compatible IDE can be used on the Raspberry Pi. Any text editor, such as Vim, can be used to program directly in the terminal.
- You can essentially build your own Arduino board using the open-source hardware and software files from Arduino. Because the Raspberry Pi isn’t open-source, this isn’t an option.
- Although the genuine Arduino UNO costs $23, countless Arduino clones are available for less than $4. When it comes to Raspberry Pi, the initial SBC costs roughly $35, while the latest Raspberry Pi 4 Model B comes in three distinct pricing ranges ($35, $55, and $75) depending on RAM configuration.
Both Arduino and Raspberry Pi have advantages and disadvantages. The best option for you will be determined by the nature of your job and your budget. Arduino is ideal for automating repetitive chores such as opening and closing doors, turning on and off lights, etc. Arduino should be your first pick if your project has any repeating elements and requires generating output depending on sensory inputs.
Raspberry Pi is ideally suited for complex jobs such as controlling complex robots, weather monitoring, and internet posting. The Raspberry Pi is the answer if your project requires advanced capabilities and an internet connection.
